How to make a portable shortwave antenna

Shortwave receivers are widely used when hiking or by hams who like to communicate with people all over the world via these radio devices. If you are going to use a shortwave receiver, good wave reception is essential. In this article, we will describe how to make a portable shortwave antenna.

Materials

- Building wire or black iron wire.

- Cable number 16 (preferably any type - flexible and lightweight cable - can be used).

- Telephone cable.

Mounting of the portable shortwave antenna

Before we begin, it is extremely important to warn that we must never attach our antenna to the power line, as the shock can be lethal. Now, with this warning in mind, we proceed to describe the assembly of our portable antenna, which has three well-defined parts: the hook, the antenna body and the coupling winding (if necessary).

Electrical assembly of the shortwave antenna

We started to put together our antennaThe hook should be placed on the branch of a bush, on a window frame or on a clothesline, and it should be used to create a good hook. To create the ideal hook, we take approximately 30 cm of construction wire and bend it into a hook, leaving an eyelet to connect the body of the antenna or simply take a hook used for hanging clothes (just the hook).

Hook for attaching the shortwave antenna

Once the hook is made, we proceed to create the body of the antenna, which is simply an extension of number 16 wire. We will only have to use one side of the wire, as these wires are double, so we take about 6m of wire and loop one end of it to the eyelet of the hook. While the other end, we place it in the antenna input of the shortwave receiver. In case you do not have this type of input, we must make a coupling winding.

Connecting the antenna to the hook

Making the coupling winding is very simple, we remove the sheathing from several metres of telephone cable. Once this is done, we remove the insulation from the telephone cable about 2 cm from one end and connect it to the free end of the antenna body, reinforcing the connection with electrical tape.

Connecting the antenna to the winding cable

Now, we unfold the antenna of the radio receiver and make a winding with the telephone wire, about 30 to 40 turns, and we have our winding ready, it only remains to place the hook on a tree branch and test our portable shortwave antenna.

It should be remembered that the longer the body of the antennaIf you are not able to receive programmes, the reception of programmes will be much better.

    How many metres of copper wire can be added to an inverted "L" antenna to make it work properly?

    Hello greetings, I am a follower of Shortwave. My receiver is a Satelite 2100, Grundy brand. And a Philco Tropical tube receiver. But lately, the shortwave is getting a lot of noise.

  3. I have put a cable of those that serve to plug the loudspeakers in form of rhombus in my window, I have put an eyebolt in the centre of each side of the window, with a thin rope (thread of Bramante) I have tied the vertices of the rhombus to the eyebolt leaving about 5 cm of separation between the eyebolt and the loudspeaker cable, at the end from one of the vertices of the rhombus I have taken the cable to the telescopic antenna of the receiver, and with a crocodile clamp I have connected it, the result in short wave has been spectacular, I receive stations from Cuba, China, Romania etc. I receive stations from Cuba, China, Romania etc. and above all I receive very well on forty metres, here I receive amateur radios from all over Europe and even America. My receiver is a Tecsun s2000 and my QTH is in Malaga city, on the third floor of a block of seven.

  4. It still serves the general purpose Mr. Hertz. People who just want to listen to the radio don't need to work at nasa. Those who want a specific antenna will do something else, and I find the article more useful for those who have a home radio and want to listen to shortwave better, than a pretentious and absurd criticism.

    The shortwave is very useful to be in the field...this antenna is very good...thank you very much.

    1. That's a mess. To receive a radio station better, the antenna must be resonant at the frequency at which you want to receive. These random calculations do not necessarily improve reception. There are hundreds of sites where you can find out how to make an antenna for reception on the shortwave bands with a good foundation and optimum performance.

      1. There are ways of putting things and yours is not the best Mr. Hertz. At least this is useful for anyone who wants to listen to shortwave with a home radio, nobody proposed that this was a radio telescope.
